SUSE-SU-2021:0801-1

This update for glib2 fixes the following issues:

• CVE-2021-27218: g_byte_array_new_take takes a gsize as length but stores in a guint, this patch will refuse if the length is larger than guint. (bsc#1182328)
• CVE-2021-27219: g_memdup takes a guint as parameter and sometimes leads into an integer overflow, so add a g_memdup2 function which uses gsize to replace it. (bsc#1182362)
